IPC: G11B11/10
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To miniaturize and simplify the information recorder by mounting a magnetic head and optical head for a magneto-optical disk and a magnetic head for a floppy disk on one head supporting body. SOLUTION: The magnetic head 2 for the magneto-optical disk for the purpose of recording and reproducing information on the magneto-optical disk and the magnetic head 1 for the floppy disk for the purpose of recording and reproducing information on the floppy disk are mounted on one head supporting body 3. The device having this head supporting body 3 for using a discoid recording carrier is capable of recording and reproducing both the magneto- optical disk and the floppy disk by this one device. In this case, during operation of one disk, the other head is desirable to be floated from the disk. In addition, a disk inserting hole can also be used for the magneto-optical disk and the floppy disk in common. Consequently, the device can be miniaturized and also an information recording system can be simplified.
